A Man travelled a distance of 61 km in 9 hours. He travelled partly on foot at 4 km/hr and partly on bicycle at 9 km/hr. What is the distance travelled on foot? | [
"87",
"38",
"127",
"16"
] | D | Let the time in which he travelled on foot = x hr
Then the time in which he travelled on bicycle = (9 - x) hr
distance = speed x time
⇒4x+9(9−x)=61⇒4x+81−9x=61⇒5x=20⇒x=4⇒ distance travelled on foot = 4x=4×4=16 km

A trader wants 10% profit on the selling price of a product whereas his expenses amount to 15% on sales. What should be his rate of mark up on an article costing 9? | [
"100⁄3%",
"20%",
"30%",
"None of these"
] | A | Let the SP of the article be x
Expenses = 15% of x = 0.15x
Profit = 10% of x = 0.10x
CP = 9 (given)
Therefore, 9 + 0.15x + 0.1x = x ⇒ x = 12
∴ % increase for marked price = 12−9/9×100=100/3%
